Actress Laura Sadler's co-star Art Malik today sent her his "prayers" as she was fighting for life in hospital.

Sadler, 22, who plays Sandy Harper in BBC1's Holby City, was in a "critical" condition after falling from a balcony.

She was found at the foot of a house in Holland Park, west London, early yesterday.

Malik said: "I'm sure myself and every member of the cast and crew is praying for her, and my thoughts go out to her and her family."

The actor, who is about to make his debut in the BBC1 drama as Professor Zubin Khan, added: "My first episode goes out tomorrow and my first line was, `Morning Sandy'. She (Sadler) was the first person I worked with."

Actor George Calil, who plays her on-screen boyfriend, was last night released on police bail pending further inquiries after he was arrested in connection with the incident yesterday. A spokesman for Scotland Yard said: "Police were called by ambulance staff at 6.30am to reports that a woman had fallen from a second floor balcony.

"The victim, who is believed to be in her early 20s, was taken by ambulance to the new Charing Cross Hospital where her condition is understood to be critical."

He added: "A 30-year-old man was arrested in connection with the incident. He has since been released on police bail to return in mid-July pending further inquiries."

Calil plays Sandy's drug dealer boyfriend Sean Hunt in the hit medical drama, a spin-off from the hospital series Casualty, which attracts millions of viewers each week

Sadler, who was born on Christmas Day and raised in London, decided on a career in acting after being inspired by the likes of Marilyn Monroe. She first hit television screens in cult children's programme Grange Hill.
